Shower Thought
If one nexus tower dies, the second one should have twice as much offense(Maybe one shot small minions and 2 shot siege minions deal double dmg to champions... etc)... same defense tho, for those clutch games where you defend and still have one tower alive or the enemy team mis plays on the final push..
not a serious thread but would be an interesting change...
.. also why the hell does the nexus have mana? What does it use mana for? xd
